A method of making small ceramic spheres by discharging drops of ceramic slip onto a moving bed of powdered material. Maximum sphere density in the bed is achieved by orienting the drop nozzles angularly across the bed and inverting the bed after receiving a first layer of spheres to form a new bed surface. A simple ramp device performs the inversion.
The technical method of densifying a granular ceramic body and forming a solid material is called sintering. Sintering is to remove the voids between the particles in the body, remove a small amount of gas and impurity organic matter, and make the particles grow and combine with each other to form a new substance.
Preparation Methods of Metal Powder. Powder metallurgy is a process for preparing metal powders and using metal (or metal and non-metal mixture) powder as raw materials to form parts and products by molding and sintering. As the main raw material of the industry, metal powder is widely used in the fields of machinery, metallurgy, chemical industry, and aerospace materials.
